Control panel for determining the (water) permeability or the permeability coefficient of cohesive and non-cohesive, saturated and unsaturated soils in triaxial cells and sample rings.

Modular control panel consisting of a regulator module with up to three independent precision pressure regulators and a burette module for determining the inflow and outflow of water. The burette modules can be equipped with various measuring burettes (see illustrations): low-pressure measuring burettes up to 2.5 bar, measuring burettes up to 10 bar (with and without electronic level measurement), and combinations of the available measuring burettes.
